More than six in 10 African Americans now rate race relations as "not so good" or "poor," while 53 percent of whites hold more positive views. Opinions are also divided along racial lines, though less so, on whether blacks face discrimination. There is more similarity on feelings of personal racial prejudice: Thirty percent of whites and 34 percent of blacks admit such sentiments.

At the same time, there is an overwhelming public openness to the idea of electing an African American to the presidency. In a Post-ABC News poll last month, nearly nine in 10 whites said they would be comfortable with a black president. While fewer whites, about two-thirds, said they would be "entirely comfortable" with it, that was more than double the percentage of all adults who said they would be so at ease with someone entering office for the first time at age 72, which McCain (R-Ariz.) would do should he prevail in November.

Most white Americans have no idea what it means to be black in America. Black Americans sure as hell know.
